Abstract

PURPOSE:To decrease the number of sound recording means by using the sound recording means provided in common by special number so as to sound-record the talking content. CONSTITUTION:When the talker of an extension telephone set 2 records its own talking, an extension telephone set 1 other than extension telephone sets 2, 3 is hooked off and a special number and an extension number of the extension 2 are dialed. A central controller 8 closes a speech path tying the extension telephone sets 1, 2 and a recording control trunk 6, a sound recorder 7 is started via the recording control trunk 6 and the talking between the extension telephone sets 2, 3 is sound-recorded by the sound recorder 7 via the recording control trunk 6. When the extension telephone set 2 requiring the sound- recording of talking is hooked on, the sound recorder 7 is stopped by the central controller 8 via the trunk 6. Thus, the sound recording of talking is controlled by a talking part requiring it.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to means for recording telephone calls at the will of an extension subscriber, which is housed in a storage program controlled switching system.

〔overview〕

The present invention is a means for recording the contents of a telephone call on an extension telephone housed in a storage program control type exchange. This makes it possible to reduce the

[Conventional technology]

Conventionally, when subscribers of a storage program controlled switching system record their calls, a recorder is installed for each subscriber.

[Problem that the invention seeks to solve]

When a subscriber records a call using such a conventional switch, there is a problem in that the number of recorders becomes excessive.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate such drawbacks and to provide a storage program controlled exchange equipped with means for recording on a common recorder.

(Means for Solving the Problems) The present invention provides a storage program control switching system that accommodates extension telephones, which includes a recording means, a trunk to which the recording means is connected, and a special number operation from the extension telephone during a call. and connecting means for connecting call information of the extension telephone to the trunk based on the telephone number.

[For production]

When a subscriber number requiring call recording is dialed together with a special number from a telephone near a subscriber requiring call recording, the subscriber's call is connected to a recorder through a recording control trunk and recorded.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

In addition to a storage program controlled switch including a conventional originating register trunk 5, this embodiment also includes a recording control trunk 6 and a recorder 7.

Now, FIG. 1 shows a state in which an extension telephone 2 and an extension telephone 3 are communicating. At this time, when the caller on extension telephone 2 attempts to record his/her own call, as shown in FIG.
When the user goes off-hook and dials the special number and the extension number of the extension telephone 2, the central control unit 8 closes the communication path connecting the extension telephone 1, the extension telephone 2, and the recording control trunk 6. Then, the recorder 7 is activated, and the conversation between the extension telephones 2 and 3 is recorded in the recording m7 via the recording control trunk 6, as shown in FIG. Further, when the extension telephone 2 that requires the recording of a call goes off-hook, the central control bag W8 stops the recorder 7 via the recording control trunk 6. This allows call recording to be controlled by the caller who requires it.

After the call ends, by performing another special number operation, this recording control trunk can be called up and recorded information can be played back and listened to.

In addition, although an example of mutual extension lines is shown here, extension lines and central office lines,
The present invention can also be applied to extension lines and middle lines.

〔Effect of the invention〕

As explained above, the present invention provides a recording control trunk in a storage program control type exchange and connects a recorder to it, thereby allowing all subscribers of the exchange to share the recorder. This has the effect of significantly reducing the quantity.
